JOHN BROUGHTON, OF BROOKLYN, NEW YORK, ASSIGNOR TO DANIEL H. FITZGERALD,OF SAME PLACE.

SHUTTER-BOWER.

SPECIFICATION forming part of Letters Patent No. 233,974, dated November2, 1880.

Application filed April 3, 1880. (No model.)

To all whom it may concern:

Be it known that I, JOHN BROUGHTON, of Brooklyn, in the county of Kingsand State of New York, have invented certain new and useful Improvementsin Devices for Bowing Blinds, of which the following is a specification.

The object of my invention is to provide a device which may be attachedto blinds for bowing them or holding them more or less open with theirmeeting edges at any desired angle to each other.

My invention consists of two plates constructed to be attached to thefaces of window shutters or blinds, and each provided with alaterally-projecting stud, in combination with two arms or levers ofunequal length pivoted, respectively, to the aforesaid plates, and eacharm or lever having an eye in its end and a too substantially at rightangles to the lever at its pivotal end for overlapping the end of thelever which engages the stud and holding it thereon, all of which willbe fully hereinafter described in detail.

In the accompanying drawings, Figure 1 represents a face view of themeeting portions of two blinds having my improved device securedthereon. Fig. 2 represents a horizontal section through the meetingstiles of the blind 0 and a partial section of my device. Fig. 3

represents a face view similar to Fig.1, except that the device isadjusted to hold the blinds at a greater angle to each other; and Fig. 4represents a horizontal section through the 3 5 blind-stiles when in theposition shown in Fig. 3.

Similar letters of reference designate corre sponding parts in all thefigures.

A A designate the two meeting stiles of a pair of blinds, and B the sillof the window to which they are applied. 0 G designate two plates, whichare of the same shape and are secured one to each blind-stile. In orderto enable them to be secured quickly and cheaply in place I cast uponthe inner faces of each of 4 5 the plates 0 C one or more projectingpins or spurs, a, which enter the wood, when the screw 1), passingthrough the plate, is screwed home thus preventing the plate fromshifting laterally without the necessity of two screws.

To the plates 0 Oare pivoted arms or levers D D, and in the presentexample of my invention the same screws, 1), which secure the platesupon the stiles A A form the pivots.

The plates 0 O are provided with conical hubs or bosses 0, through whichthe screws b pass. The arms or levers fit upon said hubs or bosses, andare countersunk upon their outer faces, so as to fit loosely around thehead of the screws 1), upon which they are capable of turning freely.

From the face of each plate 0 0 projects a pin or stud, d, and near theend of the arm or lever pivoted to each plate is an eye, 6, adapted toengage with the pin or stud upon the other plate, the arm or lever beingrecessed or bowed at f to permit it to pass over the pin or stud uponthe plate to which it is pivoted.

As here represented, each arm or lever is constructed so as to form alocking device, each being provided with a toe, 9, extendingtransversely to the length of the arm or lever, and of a length to lapover the end of the other arm or lever when the eye of the latter isupon one of the pins or studs (1, so as to prevent the accidentaldisengagement of the said eye from the pin or stud.

As the toe g projects at approximately a right angle to the arm or leverit is moved to and held in a horizontal position by the tendency of thearm or lever to gravitate downward.

When it is desired to release the blinds to open or close them, the armor lever, which serves as a locking device, has only to be swungsidewise, as represented in dotted outline in Fig. 1, to release the eyeof the other arm or lever from the pin or stud d, with which it engages.

Though both the arms or levers are here represented as furnished witheyes a, one only might be provided with an eye, in which case the otherarm or lever would serve simply as a locking device, and the pin or studd upon one plate would be dispensed with.

Where only one arm or lever is used the other arm or lever might bedispensed with, and a button substituted therefor.

By my invention I provide a device which 2 waste may be attached toblinds at a small expense, and each having an eye, 0, for engaging theand will hold them locked in a partly-open postud, and a toe, g,substantially at right ansition or bowed. gles to the lever, foroverlapping the end of the \Vhat I claim as my invention, and desirelever which is in engagement with the stud,
